Balance Sheet is out because of CTA deriving on Elimination due to NetIncome(Subsidiary) Config Rule
There are translation issues because on Entity currency, Balance Sheet is matching and on Parent Currency, Balance Sheet is going out. When further analyzed, second month onwards CTA is being calculated wrongly on "FCCS_Intercompany Eliminations" member of Data Source however CTA calculation is correctly done in first month of the same year.
While analyzing Retained Earnings Current on "FCCS_Mvmts_FX_to_CTA" member from Consolidation Dimension, I found that System is not calculating proper CTA on Consol Level i.e. On Consol level i.e., Sub Consol(FCCS_ClosingBalance-Entity Currency Amt*(Average Rate - Ending Rate) + (FCCS_Mvmts_FX_to_CTA-Entity Currency *Ending Rate)
